Marine Weather and Tide Forecast for Harbor Springs, MI

SHORT TERM /THROUGH SUNDAY/
Issued at 230 PM EST Sat Jan 24 2026

Cold. Classic arctic outbreak across the eastern CONUS with 500mb height anomaly "ridge bridge" from Greenland to north of Alaska with a deepening trough over the eastern CONUS. This opens the door for arctic air to surge southward - resulting in extremely cold conditions. This pattern largely continues for the foreseeable future. Relatively benign weather across northern Michigan tonight with just some lingering light lake effect snow showers, hugging closer to the coasts with a lighter wind regime as land breezes push much of the activity offshore. This lighter wind pattern may push some better snow shower activity toward Beaver Island, which could see minor accumulations overnight.
At least partial clearing for a time tonight before clouds increase late from the south. Widespread sub zero lows with colder pockets of interior northern lower and eastern upper in the minus teens.
Temperatures modify a bit on Sunday as the core of the coldest air slides east of the area but still very cold with highs only in the lower to middle teens. The precipitation shield from the system to our south may brush southeast parts of the area/parts of Lake Huron coast with some minor snow accumulations. Model trends have shifted a bit north in recent runs, so something to keep an eye on. Otherwise, just a few light snow showers expected across the area, hugging closer to the coasts.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
Issued at 230 PM EST Sat Jan 24 2026

Little change in the overall pattern with cold firmly entrenched across the Great Lakes. Overall, this is a drier pattern than the previous few weeks with well below normal PWATs across the area for much of the week and limited moisture with any snow producing systems. One such system will slide across the area Monday night into Tuesday, producing widespread light snow but relatively minor accumulations (compared to what we have seen recently). With Great Lakes ice cover expanding rapidly, the lake effect snow machine will be greatly reduced in some areas over the coming weeks. The models have likely not fully captured this yet but think we will see that play out in their snowfall forecasts upcoming. After that aforementioned clipper, mainly just lighter lake effect snow chances the remainder of the week with continued cold weather.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Winds remain light and VRB as overnight land breeze development will continually change direction overnight before turning to the north Sunday morning.
